filling the render window with an object?

DoomiVox

is it possible to tell the renderer in 3dsmax to zoom a camera or use the current viewport to zoom in to render the scene at just the right size to allow all of the object to fit in the renderfield's aspect ratio?

for example lets say you have a box and you know the aspect ratio of the box and set your render aspect ratio to match it, is there a way of just clicking on the box and telling the renderer to zoom in and fill the render field with just that object?

EDIT:
I figured out a way using a camera and centering it to the object and offsetting it's distance to visually match up the lines on the view field...i always seem to figure these things out only moments after i type out the issue...

somewhere down to the right is something called "zoom extents". if you want a single object in your scene focused you'd have to hide the rest till you zoomed only onto the box.
